LUBRICANT.

SPECIFICATION forming part of Letters Patent No. 632,363, dated September 5, 1899.

Application filed September 24, 1896. Serial No. 606,845. (No specimens.)

To all whom it may concern:

Be it known that I, JOHN H. PEACOCK,a citizen of the United States, residing at Wilkes- Barr, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Lubricating and Cooling Compounds, of which the following is a specification.

This invention consists in a lubricating compound which is particularly adapted for application to hot bearings for the purpose of lubricating and rapidly cooling the same.

This lubricator will rapidly reduce the temperature of black hot iron, steel, or other metals, and it is particularly valuable for application to hot car-journals and hot bearings in other machinery.

In the course of my experiments I have found that castor-oil and glycerin, when combined with sulfur, as hereinafter set forth, have the peculiar property of cooling as Well as lubricating hot journals and the like and that the other oils commonly used as lubricants are not suitable for this purpose. In this application, therefore, I desire simplyto cover the composition of castor-oil (or glycerin as its equivalent) and sulfur in the proportions substantially as set forth, and I do not include as equivalents the other oils commonly used as lubricants.

In preparing the compound I take castoroil or glycerin in substantially the proportions of six and one-half pounds of caster-oil or glycerin to one pound of sulfur. These ingredients are placed in a suitable vessel and heated to the boiling-point over a slow fire and boiled for thirty minutes, more or less, until froth forms on the surface. The compound is then allowed to cool, when it is ready for use.

I do not confine myself to the exact proportions of the ingredients mentioned, as they may be slightly varied without departing from the spirit of my invention or discovery.

What I claim is A cooling and lubricating compound consisting substantially of thirteen parts of glycerin combined with two parts of sulfur, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN H. PEAOOCK.
